Columbia River Gorge: How long on the interstate?
I am thinking of touring the Columbia River Gorge this year. My plan would be to cycle down the Oregon side and come back on the Washington side. One concern is the interstate.
I am having a difficult time figuring out how many miles I would have to do on the interstate due to the changing situation with the old highway.
Can anyone give me an idea on how many miles I would need to do on the interstate?
